Recent advancements in Single Image Super Resolution (SISR) have been achieved by utilizing deep neural networks with a high number of layers. Incorporating multi-scale information is crucial in designing advanced super-resolution networks. In this paper, we present a novel feature upscaling method for SISR tasks which enhances the multi-scale information of images through multi-mode interaction. The multi-scale block design introduces more abundant image information, and the designed feature extraction module works in tandem with the multi-scale module to restore details in low-resolution images, thus enhancing image clarity. The static features and dynamic information in different scales of the image are fused and interacted through the local channel attention module to adjust the importance of different modes in recognizing different actions, thereby improving the final performance of the model. Numerous experiments confirm that our model achieves higher accuracy on Set5, Set14, B100, and Urban100 datasets compared to other state-of-the-art methods, while requiring relatively low computational and memory resources.
